SCARF-PIN.

PECIFICATION formingpart of Letters Patent No. 746,049, dated December 8, 1903.

Application filed September 29, 1908. Serial No. 175.064. No model.)

To all whom it may concern:

Be it known that I, GEORGE W. DOVER, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvement-s in Scarf-Pins, of which the following is a specification, reference being bad therein to the accompanying drawings. 7

My invention relates to scarf-pins, and has for its object, in'addition t0 the ends commonly sought by such devices, a method of uniting the pin-stem with the head of the scarf-pin without the use of solder. By the methods heretofore employed the heating of the metals incident to the soldering operation has tended to weaken the scarf-pin at that point whereon the greatest strain is naturally brought.

The attainment of the ends above indicated is secured by the invention hereinafter described, and illustrated in theaccompanying drawings, Wherein Figure 1 is the side elevation of a blank from which the pin-stem is to be ultimately formed; Figs. 2 and 3, similar elevations of the same in various stages of mechanical development; Fig. 49a side View of my completed scarf-pin; Fig. 5,'a vertical section of the same upon line 00' 00 of Fig. 6, showing parts of the pin and spur broken away; and Fig. 6,a transverse section of the same on line y 'y of Fig. 5.

Like, reference-letters indicate like parts throughout the views.

My new device is constructed as follows: A cylindrical blank A has formedat one side of its center a loop 0, leaving a section of the blank 1) upon one side of the loop and a longer sectiona upon the other side. Theloop portion of the blank thus treated is next flattened, as shown in Fig. 2, in rectangular dies, which leaves the lower extremity c of the flattened portion a smooth rectangular sur face. The flattened portion is next pierced with an opening d, which operation completes the pin-stem.

Upon the back of the scarf-pin head B rise two ears 6, provided-with transverse perforations fto receive a dowel-ping, which traverses these openings and the opening d of the pin-stem. It will be observed that, as

illustrated, the opening 01 in the pin-stem is of somewhat greater diameter than the perforations f of the lugs. This formation admits of a more secure frictional engagement of the united parts than if the openings were all of equal diameter-,yet ,it will be understood that this matter of detail is not vital, as an operative union maybe effected by the employment of openings of equal diameter.

As shown above, at any convenient stage of the formation of the pin-stem the shorter section b may be pointed to form the usual spur, and the portion a may be pointed to form the pin portion.

It will be noted from the above description that the use of solder has been entirely dispensed with and that a perfectly firm and unyielding union is efiected by means of the the rear face of the head B.

Having described my invention, what I pressure of the flat face 0 of the lug 0 upon 3. In a scarf-pin, the combination with a head of ears upon the head, a stem, a lug upon the stem located intermediate the cars, a dowel-pin traversing the lug and ears, and

means upon the lug for retaining the parts against angular displacement.

4. In a scarf-pin, the combination with aa pin traversing the hole and perforations and tightly engaging the lug and ears.

In testimony whereof I have affixed my signature in presence of two witnesses.

. GEORGE W. DOVER.
